WebApr 12, 2024 · Herein, we have studied the exciton dynamics of a novel fused ring π-conjugated molecule (YS3) in solution and film states by spectroscopic measurements.This molecule incorporates dithienonaphthobisthiadiazole as a core unit that is a two-dimensionally π-extended fused ring.As a result, we found a long exciton lifetime in YS3 … WebPi (π) bonds form from the side-by-side overlap of two p orbitals. The plus signs indicate the location of the nuclei. A pi bond (π bond) is a type of covalent bond that results from the side-by-side overlap of two p orbitals, as illustrated in Figure 4. In a π bond, the regions of orbital overlap lie on opposite sides of the internuclear axis. pon creamy tomato chicken
